Mickelopteris cordata 

Mickelopteris cordata grows from short erect rhizomes covered with brownish narrow scales. The fronds are of two types. Fertile (spore-bearing) fronds have stipes (stalks) that are usually much longer than those of sterile fronds. The blade (lamina) of the frond is usually 3–6 cm (1.2–2.4 in) long by about 2–4 cm (0.8–1.6 in) wide, with a heart-shaped base and a somewhat rounded apex. It is held at an angle to the stipe. Fronds are brownish green on the upper side, brown on the lower side.
